That mutation tacks on an extra type of cone to the usual three varieties humans are born with in their retinas ... People with normal color vision posses 3 cones in their eye. But there are some rare cases when people can have 4 cones (Tetrachromacy). These people, some of them will notice the shades difference in the scene through their eye. And the rest won't notice it, because simply their 4th cone is activated in the close peak value with the the L-cone.Jordan estimates that 12% of women are candidates for tetrachromacy but that functional tetrachromats are rarer - 2-3% by some estimates [4].
